3.4 TAPE GLAZING <br /> A. Position tapes on fixed stops so that when compressed by glass their exposed edges are flush <br /> with or protrude slightly above sightline of stops. <br /> B. Install tapes continuously but not in one continuous length. Do not stretch tapes to make <br /> them fit opening. <br /> C. Where framing joints are vertical,cover these joints by applying tapes to heads and sills first <br /> and then to jambs. Where framing joints are horizontal,cover theseaoints by applying tapes to jambs and then to <br /> heads and sills. <br /> D. Place joints in tapes at corners of opening with adjoining lengths butted together,not lapped. <br /> Seal joints in tapes with compatible sealant appmved by tape manufacturer. <br /> E. Do not remove release paper from tape until just before each lite is installed. <br /> F. Center glass lites in openings on setting blocks and press firmly against tape by inserting <br /> dense compression gaskets formed and installed to lock in place against faces of removable stops. Start gasket <br /> applications at corners and work towazd centers of openings. <br /> G. Apply cap be�d of elastomeric sealant over exposed edge of tape. <br /> 3.5 SEALANT GLAZING(WE1� <br /> A. Install continuous spacers between glass lites and glazing stops to maintain glass face <br /> cleazances and to prevent sealant from extruding into glass channel weep systems until sealants cure. Secure <br /> spacers in place and in position to control depth of installed sealant relative to edge clearance for optimum sealant <br /> performance. <br /> B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or <br /> bond of sealant to glass and channel surfaces. <br /> C. Tool exposed surfaces of sealants to provide a substantial wash away from glass. Install <br /> pressurized gaskets to protrude slightly out of channel to eliminate dirt and moisture pockets. <br /> 3.6 LOCK-STRIP GASKET GLAZING <br /> A. Comply with ASTM C 716 and g�sket manufacturer's printed recommendations. Provide <br /> supplementary wet seal and weep system unless otherwise indicated. <br /> 3.7 PROTECTION AND CLEANING <br /> A. Protect exterior glass from breakage immediately after installation by attaching crossed <br /> streamers to framing held away from glass. Do not apply markers to glass surface. Remove nonpermanent labels, <br /> and clean surfaces. <br /> B. Protect glass from contact with contaminating substances resulting from construction <br /> operations including weld splatter. If,despite such protection,contaminating substances do come into contact with <br /> glass,remove them immediately as recommended by glass manufacbuer. <br /> C. Examine glass surfaces adjacent to or below exterior concrete and other masonry surfaces <br /> at frequent intervals during construction,but not less than once a month,for build-up of dirt,scum,alkali deposits, <br /> or stains,and remove as recommended by glass manufacturer. <br /> D. Remove and replace glass that is broken,chipped,cracked,abraded,or damaged in any way, <br /> including natural causes,accidents and vandalism,during construction period. <br /> Page 7 of 8 <br />
